Abstract

An optical disk drive comprises a core body, a guide bar, a pick-up head and an impact-reducing mechanism. The core body has an operation zone. The guide bar is fixed to the core body. The pick-up head is movably supported by the guide bar to read/write an optical disk in the operation zone. The impact-reducing mechanism is disposed outside the operation zone to resist the pick-up head, when the pick-up head moves outside the operation zone along the guide bar.
